MACHINE FOR wmome YARN.

SPECIFICATION forming part of Letters Patent No.400,118, dated March 26, 1889.

Application filed November 17, 1886. Serial No. 219,142. (No model.) Patented in England January 9, 1884, No. 1,051, and December 30, 1885, No. 16,008; in Germany December 20, 1885, No. 36,038, and in Austria-Hungary October 19, 1886, No.

T0 60% whom it may concern.-

Be it known that I, FERDINAND RossKo- THEN, a subject of the Queen of Great Britain, and a resident of Accrington, in the county of Lancaster and Kingdom'of England, have invented certain new and useful Improvements in Yarn Vinding Machinery, of which the following is a complete, clear, and exact description, setting forth in general and in detail the invention,the said invention having been patented to me in the following countries, to wit: Great Britain, No. 1,051, January 9, 1884:,

and No. 16,008, December 30, 1885; Germany,

No. 36,038, December 20, 1885, and Austria Hungary, N 0. 21,37 6, October 19, 1886.

This invention relates to machinery or apparatus employed in winding yarn, and has for its objects, first, to enable the yarn to be wound into a form which will bear handling or ordinary use without the employment of flanged bobbins or reels, and, second, to prereadily understood and carried into practical effect, I have hereunto appended the accoming drawings,"having the elements or parts of the figures thereon indicated by letters and figures, and reference is hereinafter had thereto.

Figure 1 is a diagrammatic representation of a coil of yarn wound according to these improvements. Fig. 2 is a side and end view of the same, with indications of the respective positions of the thread-guide at diiferent periods of the winding. Fig. 3 shows how the coned ends are obtained. Fig. 4 shows two contact driving-shafts. Figs. 5 and G are different views of a frame in which the coils are propelled, and Fig. 7 is a view of mechanism for obtaining the motion of the threadguide.

According to this invention, the yarn proceeds from the thread-guide at a tangent to the spiral of yarn being wound upon the coil at any given instant; hence the thread-guide must always be in advance of the point of contact of the yarn with the coil as it is being wound on. This being so, the thread-guide will be at the position 1 when the spiral of yarn reaches the end of the coil, and in order to bring it to the correct point for the return spiral the thread-guide must suddenly be shifted to the position marked 2. Correspondingly at the other end of the coil the threadguide has similarly to be shifted from the position 3 to 4. Between the points 2 and 3 and 4 and 1, respectively, the thread-guide moves at sucha speed as will wind a quick and uniform spiral upon the coil.

of yarn, they are formed with coned ends, as represented in Fig. 1. To secure this result, the distance between the thread-guide and the coil of yarn is increased as the latter is built up and as diagrammatically represented in Fig. 3, where the full lines represent the coil when half wound and the dotted lines indicate it as complete. In the half-wound coil the length of the yarn from coil to guide is from a to b, but in the complete coil the length is from a to c. The effect of this lengthening is to shorten the range of each successive spiral and to produce a'coil having coned ends, as indicated in Fig. 1.

To economize space, I sometimes arrange contact driving-shafts across the frame at right angles to the ordinary position, as shown in Fig. 5, and drive them by means of a drum or of pulleys on a shaft which extends in the direction of the length of the frame,

and drive one, two, or more coils by each end of each contact driving-shaft. Referring to Fig. 5, it will be seen that one coil may be placed between each two adjoining brackets, f, thus making two on each end of each shaft. Fig. 4 is a plan of this arrangement, h representing the contact-shafts, and '2' the position In order to increase the stability of the coils of the main driving-drum. In Fig. 0 the front view of this arrangement is shown, like letters indicating the same parts in these figures.

On the ends of the brackets f there may be formed arms 7:, which serve to support the coils while the attendant is piecing broken ends of yarn.

To enable the attendant to stop the rotation of the shafts h singly while removing a coil for piecing or other purposes, a hand wheel, 7, may be fixed upon each end of each shaft, whereby the rotation of the shaft may be arrested at any time.

Fig. 7 is a view of the devices for obtaining the motion of the thread-guide. Upon the thread-guide rod or its equivalent 8 there is mounted a light lever, 1', by means of the pin pivot or fulcrum t, to the upper end of which is attached the pigtail or thread-guide g. In its position of rest this light lever may be kept vertical by means of a spring, 9", attached to its lower end, the spring itself being carried by the thread-guide rod on lugs therefrom, as in Fig. '7. Since the lever moves with the rod 8, the motion of the point 9 will ordinarily be equal to the motion of rod 8; but if the lower end of the lever is prevented from partaking of the motion of rod 8 by contact with a fixed pointsuch as m-the action of the spring is overcome and the lever assumes the inclined position indicated in the full line 9 at the right of Fig. 7.

It is obvious that the speed of the point g may be varied relatively to the speed of rod 3 by varying the proportions nt and tg of the lever, or, on the contrary, if the point 9 is moved precisely as required for correct winding; the speed of the rod 3 may be re duced to any reasonable amount by choosing suitable proportions for the lever. If, for example, a t: n g is made equal to 1 4, the speed of the rod 8 may be reduced to onefourth of the speed required for g, so long as the point 11 is prevented by the fixed or adjustable stop m from following the motion of .9. When the motion of the rod is reversed, the action of the spring restores the lever to the vertical position, and the point a being no longer in contact with or controlled by the stop on the speed of point g becomes equal to that of rod 3 until it is again accelerated by contact of the point 72. with the fixed point m at the opposite end of the stroke. By this combination or arrangement the heavier portions of the threadguiding motion or apparatus may be reversed at a reduced speed, while the requisite sudden reversal is effected by the light lever. The vibrations, which are a great defect in existing apparatus of the like character, are thus greatly diminished, and the thread-winding machine may be run at a high speed with safety.

I claim as my invention- In a machine for winding yarn, a threadguiding motion consisting of the combination of a movable thread-guide rod, .9, a pivoted lever mounted thereon, a pigtail or threadguide, g, mounted upon the upper end of said lever, a retractile spring for said lever, attached to its lower end and to the said threadguide rod, and a stop, m, for said lever, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
